“It will not only take riders through a series of nose-dives, banks, dips and turns at a speed of 37 miles per hour, but while doing so, continually rotates on its axis! Though this thrilling whirlwind lasts only a little over a minute, it covers 1,411 feet of track that includes a drop of 39 feet, making you a human twister!”–Knott’s Berry Farm Press Release

Sierra Sidewinder was designed by Mack and will feature two trains with four cars instead of individual cars like the Big Spin coasters and Mr. Six’s Pandemonium. Check out the press release for more information and these early construction photos of Sierra Sidewinder.
